CR 48, Midkiff Bridge Replacement (Lincoln County, WV)

Home / Projects / CR 48, Midkiff Bridge Replacement (Lincoln County, WV)

On this project, HMB was contracted to design a bridge replacement for CR 48 over the Guyandotte River. The 300-foot long bridge serves a two-lane roadway. The new, three-span (85'-130'-85') bridge replaced a through-truss span founded on large, reinforced concrete wingwall abutments. The superstructure is a weathering steel 3 girder system.  Deck drains were used in the end spans to intercept water running off the bridge ends. The substructure consists of bent pier caps with two 42” columns on 48” drilled caissons. The roadway vertical alignment required a vertical curve on the bridge rather than a straight grazed to avoid pressure flow for extreme flood events. The roadway also involved tying into two local roadways between the end of the bridge and the tie down location at the existing railroad at grade crossing. Traffic was maintained on the existing bridge during the new bridge construction and did not require any road closure.
